Standard combined bearings are design and manufactured according to standard parameters of roller bearings. This series can be classified as relubricable ZZ and 2RS two structures. The outer ring usually has a curve shape to countervail the geometric errors of the guide and connection couplings. Bearing are normally greased with No. 3 lithium based grease. In case bearings will be used in special environment, eg. high temperature, please contact us.
